The heat dissipating member includes a plurality of heat dissipating fins for dissipating heat generated by the light-emitting members. The lamp housing has an opening provided in a mounting position of the guide plate, so that ambient air can enter the lamp housing via the opening. The ambient air is then guided by the guide plate to the heat dissipating member, so that heat generated by the heat dissipating member can be taken away by the ambient air. However, the lamp housing must provide a definite space for mounting of the guide plate, so that the volume of the entire lamp housing is increased. Further, the provision of the guide plate also increases the cost of the entire headlight device.

By using the ambient air to flow through theheat dissipating member 4, heat dissipation effect can be enhanced. Thus, theheat dissipating channel 3 on one hand serves to dissipate heat, while on the other hand serves to permit heat exchange between theheat dissipating member 4 and the ambient air. Further, theheat dissipating member 5 on thesecond lighting unit 2 can be similarly guided by the air flow to enhance heat dissipation effect thereof. - In summary, because the first and
second lighting units heat dissipating channel 3 is formed therebetween. Theheat dissipating channel 3 has a heat dissipation and flow guide effects, and uses the ambient air to assist theheat dissipating member 4 in dissipating heat. Since there is no need for provision of guide plates in this embodiment, the cost of the guide plates and the mounting space thereof can be saved.
